“…This is typical for rough turning operation at low speeds [12]. However, at the higher speeds (at finishing operation), the buildup is removed from friction surface [13] and cratering becomes predominant [14]. Presumably, efficiency of the TiB 2 coating could strongly vary under different cutting speeds.…”

Tribological phenomena and tool wear mechanisms during machining of hard-to-cut TiAl6V4 aerospace alloy have been investigated in detail. Since cutting tool wear is directly affected by tribological phenomena occurring between the surfaces of the workpiece and the cutting tool, the performance of the cutting tool is strongly associated with the conditions of the machining process. The present work shows the effect of different machining conditions on the tribological and wear performance of TiB 2 -coated cutting tools compared to uncoated carbide tools. FEM modeling of the temperature profile on the friction surface was performed for wet machining conditions under varying cutting parameters. Comprehensive characterization of the TiB 2 coated vs. uncoated cutting tool wear performance was made using optical 3D imaging, SEM/EDX and XPS methods respectively. The results obtained were linked to the FEM modeling. The studies carried out show that during machining of the TiAl6V4 alloy, the efficiency of the TiB 2 coating application for carbide cutting tools strongly depends on cutting conditions. The TiB 2 coating is very efficient under roughing at low speeds (with strong buildup edge formation). In contrast, it shows similar wear performance to the uncoated tool under finishing operations at higher cutting speeds when cratering wear predominates.

“…In addition, Eckstein et al [15] describe a "slower wear progression" when working at high cutting speeds as compared to conventional milling, whereas the norm is an exponential increase in tool wear at elevated speeds. According to research, the wear mechanisms and mechanical issues of Ti6Al4V still require thorough study [16]. Furthermore, it is indicated [17] that additional research is required to determine the dominant tool wear mechanisms of PCD tool material.…”

Tool performance of conventional tools is poor and a major constraint when used in milling titanium alloys at elevated cutting speeds. At these high cutting speeds, the chemical and mechanical properties of Ti6Al4V cause complex wear mechanisms. In this paper, a fine-grain polycrystalline diamond (PCD) end mill tool was tested, and its wear behavior was studied. The performance of the PCD tool has been investigated in terms of tool life, cutting forces, and surface roughness. The PCD tool yielded longer tool life than a coated carbide tool at cutting speeds above 100 m/min. A slower wear progression was found with an increase in cutting speeds, whereas the norm is an exponential increase in tool wear at elevated speeds. Observations based on scanning electron microscope (SEM) and energy dispersive spectroscopy (EDAX) analysis suggest that adhesion of the workpiece is the wear main type, after which degradation of the tools accelerates probable due to the combined effect of high temperature degradation coupled with abrasion.

“…Several attempts have been made to analyze tool-chip adhesion and layer formation on the micro scale using various methods including Raman spectroscopy [1], secondary ion mass spectrometry (SIMS) [2], and also a set of complementary techniques for characterization in more quantitative terms. An example of the latter can be found in a recent study [3] combining the use of 3D white light interferometry for quantifying adhesion through the layer of reaction products, scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), and wavelength dispersive x-ray spectroscopy (WDS) to describe the metallurgical state.…”

A method based on focused ion beam milling and analytical electron microscopy to investigate the nature of the tool-chip interface is presented. It is employed to study toolchip interfaces of the rake face of a (Ti 0.83 Si 0.17 )N coated sintered c-BN insert after turning operation of case-hardened steel. Analytical electron microscopy shows the presence of a smeared adhered layer on the coating, which consists of steel elements from the work-piece, oxygen, and Si and N, most likely originating from the coating.2
